FIRE-EXTINGUISHING COMPOUND.

Application filed January 6, 1885. Serial No. 152,174. (No specimens) T0 aZZ whom it may concern.-

Be it known that I, GEORGE WILLIATWI ED- DISON, a resident of New York, county of New York, and State of New York, have invented certain new and useful Improvements in Fire- Exterminating Compounds, of which thefollowing is a full, clear, and exact description. Take of vinegar, ten gallons; oil of vitriol, ten pounds; sulphate of copper, one pound; chloride of zinc, one pound; sulphate of ammonium, one pound; chloride of potassium, one pound; alum, one pound; phosphorus, one pound. Mix the ingredients together very slowly in the order named above, and should eft'ervescence take place discontinue until it ceases. Then proceed as before until all the ingredients have become assimilated. Then decant in green glass bottles or jars or rubber bags.

Should a fire occur, throw the compound upon the flames, and the action of the compound upon the flames completely and rapidly exterminates the fire.

Having fully described my invention, what I claim, and desire to secure by Letters Patent 25 of the United States, is-

The herein-described composition of matter to be used for exterminating fires, consisting of vinegar, oil of vitriol, sulphate of copper, chloride of zinc, sulphate of ammonium, chlo- 3o ride of potassium, alum, and phosphorus, in the proportions specified.

In testimony that I claim the foregoing I have hereunto set my hand in the presence of two witnesses.

GEORGE WILLIAM EDDISON.
